DRAFT APPARATUS.

SPECIFICATION forming part of Letters Patent No. 717,786, dated Januaryfi, 1903.

Application filed April 24; 1902. Serial No. 104,438. on model.)

To all whom, it may concern:

Be it known that I, MICHEL WEIREs, a citizen of the United States, residing at Allison, in the county of Butler and State of Iowa, have invented certain new anduseful Improvements in Draft Apparatus, of which the following is a specification.

This invention relates to the draft apparatus of carriages and the like; and the object of the invention is to produce a neat and strong device and so arranged that no twisting strain is brought to bear upon either the singletrees or the doubletree.

The nature of the invention will fully appear from the description and claims following, reference being had to the accompanying drawings, in which-- Figure 1 is a view in perspective of a draft apparatus embodying my invention. Fig. 2 is a longitudinal section of the same'central to the king-bolt. Fig. 3 is a section central to the king-bolt, but longitudinal to the doubletree.

In the drawings, A is a carriage-tongue of the usual type. This is provided with a bracket 13, corresponding to an ordinary hammer-strap, and a reverse bracket C in the nature of a stirrup setting under the bracket B. This has extensions 0 and C the latter of which extends under a similar extension B of the other bracket. Both are secured to the tongue by bolts 1). Through the upper portions of the brackets passes a king-bolt E, holding the doubletree in place. The extension 0 takes the wear of the doubletree. The doubletree is composed of a central block of hard wood F and a pair of iron or steel bars F and F attached to it by rivets G. The bars taper toward the outer end, where they embrace the singletrees H and take pivot-bolts I, holding the singletrees. In practice the lower bar of the doubletree is made straight; buta curve is formed in the upper one at F near each end of the block F. This gives room for the hand'of the operator in hitching and unhitching the traces and admits of the traces moving back and forth Without rubbing whether taut or slack.

Besides being very strong and durable the device is such that the strain on the doubletree is direct and central without any twisting strain on either theking-bolt or singletree-bolt connections.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In draft apparatus, a doubletree composed of a central block of wood and a pair of tapered bars of iron or steel riveted to it, forming a fork at each end to take the singletrees.

2. A doubletree formed of a central wooden block and a pair of tapered iron or steel bars riveted to it, top and bottom, forming a fork at each end to take a singletree, the fork being spread near the ends of the block, substantially as and for the purpose set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
